摘要

A novel technique providing noise resistance in digital wireless communication systems by using bispectrum-organized modulation, demodulation procedure performed by new third-order signal detection test statistic and decision making by estimation of signal magnitude bispectrum (bimagnitude) peak value is proposed. Results of computations of bit error rate obtained both for the additive Gaussian noise and mixture of the Gaussian and impulsive noise demonstrate considerable improving of noise immunity performance for proposed bispectrum-organized modulation comparing to the common frequency shift keying (FSK).
